I didn't see useful information from dmesg. (In reply to comment #5)

Attached are the dmesg and messages logs. The network connection was lost twice in this time.

'watch -n 1 rfkill' did not work so I used 'rfkill event' instead.

I also discovered that this bug affects 2.6.39 from Debian backports. (http://packages.debian.org/squeeze-backports/linux-image-2.6-686)

Let me know if you need any more information/testing.

Sorry for my command is wrong, please use: 'watch -n 1 rfkill list' Then, please monitor does there have any state of rfkill changed (soft/hard block) when issue happen? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I believe acer-wmi still running the polling thread to read the hardware status on your machine, and the wmi or EC register might response wrong status. Please kindly share your acpidump and dmidecode to me, just attach on this bug: # acpidump > acpidump.dat # dmidecode > dmidecode.log Thanks -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Did you do anything when you test my patch? e.g. press Fn function key to enable/disable wifi? or set block/unblock on rfkill for wifi? Or, actually, you didn't do anything, just put the machine there after system boot?

When I tested your patch, I did not change the wifi state. The only thing I did was unplug the AC power adapter as this would sometimes trigger the bug. The instances of "state: 0" in the log seemed to be completely random to me. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
